U+01CE "ǎ" Latin Small Letter A with Caron Unicode Character

U+01CE "ǎ" Latin Small Letter A with Caron is a modified lowercase letter 'a' that incorporates a caron, or háček, a diacritical mark resembling an inverted breve placed above the character, which is used in several languages to indicate a specific phonetic value, typically a rising or falling-rising tone. This character is commonly employed in the Pinyin romanization of Mandarin Chinese to represent the third tone, known as the falling-rising tone, as in the word "nǎ" meaning "which." It also appears in other linguistic systems, such as the romanization of certain Slavic languages like Czech and Slovak, though less frequently than its uppercase counterpart. The glyph is visually distinct from the plain Latin 'a', serving as a crucial tool for accurate transcription and pronunciation in language learning, phonetics, and digital text encoding.
